Experience of fast locating and ligating renal pedicle in anatomical retroperitoneal laparoscopic radical nephrectomy

Objective:To explore the experience of fast locating and ligating renal pedicle in anatomical retroperitoneal laparoscopic radical nephrectomy.Methods:Forty-three patients treated with retroperitoneal laparoscopic radical nephrectomy were divided into the control group(21 cases) and observation group(22 cases) according to the different ways of locating and ligating the renal pedicle.The control group were treated with retroperitoneal laparoscopic radical nephrectomy,and the renal pedicle were located at the protuberance of renal dorsal side.The observation group were treated with anatomical retroperitoneal laparoscopic radical nephrectomy,and the renal pedicle were looked for along the surface of the inferior vena cava(right side) or abdominal aorta(left side).The time of locating and ligating renal pedicle,intraoperative bleeding volume,operation time,incidence rate of intraoperative and postoperative complications,number of lymph node dissected,extracting drainage tube time and postoperative hospital stay were compared between two groups.Results:All operations were successful,and no case was open operated.The time of locating and ligating renal pedicle in observation group was significantly shorter than that in control group(P<0.01),and the number of dissecting lymph node in observation group were more than that in control group(P<0.05).There was not serious complications in two groups during perioperative and postioperative period.The differences in bleeding volume,operation time,extracting drainage tube time and postoperative hospitalization time between two groups were not statistically significant(P>0.05).Conclusions:Anatomical retroperitoneal laparoscopic radical nephrectomy combined with looking for renal pedicle along the surface of the inferior vena cava or abdominal aorta can quickly locate and ligate renal pedicle vessels and improve the number of dissecting lymph node,and the anatomy and operation vision are clear.It is helpful for standardization of surgery and rapid popularization of technology.
